Here are the cultivars I could find:
'Goshiki' - This variegated form features leaves splashed or dusted with creamy white. The plant is sometimes offered by specialty nurseries and grows fairly well. 'Variegata' features a white rim around the leaves, but it's a weak grower.
'Green Vase'- This popular form is a fast grower to 70' tall with a width of 35' to 40'. It maintains a vase-shape with upright arching branches. It is taller and less broad than 'Village Green' at maturity, plus it grows more quickly. The fall color is bronze-red. It is widely considered the best selection.
'Halka' - This is one of the more popular forms, but it lacks the merit of 'Village Green' or 'Green Vase'. It reaches 50' tall with a spread of 30', but the habit is more open and loose. It lacks the dense uniformity of the other two cultivars, plus the yellow fall color does not rival their display.
'Spring Grove' - A potential rival for 'Village Green', this selection is yet to see mass production. It exhibits a distinct vase shape with tight branching. It is also ornamentally superior for its dark green leaves, red fall color and attractive peeling bark. The plant has the potential to grow 80' tall with a spread of 60'.
'Village Green' -A common plant in commerce, this form develops a straight, clean trunk and reaches 50' to 60' tall. The canopy is quite wide and dense with dark green leaves, while the fall color is rusty red. It expresses good disease and insect resistance with excellent cold hardiness. It grows quickly and vigorously as a young plant.
